tl;dr page-based linear addressing induces performance loss with complicated access policies, e.g. multilevel page tables. Mr. Kamp would prefer an object model of memory access and protection. Also, CHERI (https://dl.acm.org/doi/10.5555/2665671.2665740 https://dl.acm.org/doi/10.5555/2665671.2665740) increases code safety by treating pointers and integers as distinct types.
